Is there a better way to rework primer pockets?

Here is the story. I bought some Winchester 7.62x54 brass from Midway and I have been having some trouble. I deprimed some of them so I could tumble them to remove any excess lube. Something had been contaminating my powder and giving me all sorts of headaches and after thoroughly cleaning my dies and still having the same problem I decided that it almost had to be their fault.
The plan was deprime, tumble, reprime.
I am now finding that the primer pockets are out of spec. At least they are out of OUR specs. They are all the same, which is to say that they are all wrong.

I called Midway and they agreed to accept the return and give me a credit but that still leaves me short a significant quantity of brass that I REALLY wanted so I could handload for my M-39.

I got to looking at the situation and I did managed to ream out 20 of them with my Lyman hand reamer but it is becoming clear that there has to be a better way to do this.
Is there some sort of bulk production doohickus I can get to do a whole lot of these at once?
Also, who makes the smallest large rifle primer. There has to be some variance between manufacturers...

Thanks.

Shouldn't be any variance on primer pocket size. There is only one size of Large Rifle Primer.

I'd just buy different brass. If what you had was once fired stuff, it may have been military or some kind of proprietary primer...

Another option would be a swagger. Most cost effecive one I found is the RCBS primer pocket swagging dies. (http://www.midwayusa.com/midwayusa/applications/eproductpage.exe/showproduct?SaleItemID=447022)

What I'm running into isn't a military crimp. It is that the primer pockets aren't deep enough. I played around with them last night and I found that about 4 complete turns per case with the primer pocket uniformer will give me enough to seat a regular primer correctly. Then I kiss the pocket with my military crimp remover (2 turns) to sort of "funnel" the primer pocket because they are also a little tight that way. It has been working OK. I primed 20 more with CCI benchrest LR primers last night after going through my little procedure.

I think I might try to make this stuff work but it is going to be a whole lot of work.

Winchester 76245R, (presumably Sellior & Bellot), has a pocket that has a larger than usual fillet joining the bottom and the sides. Winchester primers will fit without all that aggravation.
The use of one of the primer pocket uniformers will allow the use of all the other primers too.

I'll have to get some Winchester primers to try in them.

Thanks.
